The existence of Battlefield 3 Premium, a paid service for the military shooter, was already leaked last weekend. However, DICE did have some new details to share during EA's E3 press conferences.

BF3 Premium allows players to pay one fee of $49.99 and get access to all five expansion packs. Back to Karkand was already released, and the other four will arrive within a year. You'll be able to play each expansion two weeks before they're officially released. Other perks include server queue priority, exclusive events, and new customization options.

EA doesn't really play up the fact that Premium is a money-saver, too. Karkand costs $15 and the future expansions probably will, too. You're therefore saving about $25 by purchasing Premium. Obviously those calculations assume that you want every bit of the game's content, though.

During DICE's presentation, they announced a few details on the last two expansions to the game. Aftermath, due in December, will take place in the city of Tehran after an earthquake. End Game will complete the DLC slate in March 2013 with the debut of motorcycles among other content.

Premium is available for purchase starting today. If you own the PS3, you can start playing Battlefield 3's Close Quarters expansion as soon as you sign up for Premium. Due to an exclusivity agreement between Sony and EA, Xbox 360 and PC gamers will need to wait until June 12th for access to Close Quarters. That expansion, which focuses on indoor combat, will be released to the public on June 19th for the PS3 and June 26th for the 360/PC.
